I’m gonna pull off the fenders and check if any bolts are loose I’ll lyk and thank you yellow looks great on the busa wish they were oem fairings tho
Exhaust leaks are easy enough to figure out. Get a spray bottle with a slightly soapy solution and squirt around the areas that might leak when it’s running. If bubbles appear it’s leaking.
My Gen 2 was ticking, louder than the video - exhaust leak at the slip-on FYI
Audio sounds more like a "wobble" than a hard knock so I would also check for an exhaust/air leak. Spray around like Wuzza advised or hover your hand around the pipes so long as it's not hot.
I would pull the fairings off and raise the tank just so you could pinpoint it better. Let us know when you find out!

A sheet of paper held around header joints will quickly show a leak too.

A 2-3 foot long piece of vacuum hose or small fuel line with one end in your ear and the other end sweeping around the engine helps locate noises.

I use one of these….
Awesome for detecting unusual noises and the location of said noises.

I have the same one, I pull the end out and that gives me a vacuum hose in both ears. I recommend the vacuum hose trick because most don’t have an automotive stethoscope like we do. They definitely come in handy.

Funny you say that about pulling the end out…I do the same lol, then I can home in on the location of the noise I’m hunting down.
I’ve always used one of these while working with cars, but when I started at a bike workshop and pulled it, I got laughed at by the other techs… they’d never seen one.
They called me ‘the doctor’ lmao.

Lol I’ve had that same reaction out of people when I put it around my neck.
My dad used a giant screwdriver to pinpoint alternator, water pump, power steering pump etc noises, he would put his thumb over the handle end and put his thumb knuckle in his ear and the flat end of the screwdriver against where he thought the noise was coming from. I’ve done it and it works lol. Of course that was way back before he bought a couple stethoscopes for us, I still have my original one from 40+ years ago.
My dad did that as well and 99% of the time he was accurate and found the source of the noise...
I recall one of my racing team mates had a GSXR Slingshot with a dry clutch....it sounded like the engine was going to fly out of it at any time......
He said he'd never ride one on the street just because of the racket it made.....especially when it got hot.
